Our leggings are pretty much one sized and they come in three different size catergories.  We broke them down so that you would have a general idea on what size would work best for you.

Small/Medium: Size 2-10

Large/X-Large:  Size 12-16

XX-Large/XXX-Large (1X-3X): Size 18-22

All of the sizes are pretty generous and they have a lot of length.
